Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a roller device for spinning machinery. Background Technology

[0002] The spinning machine includes a back roller, a middle roller, and a front roller connected to a support frame. The yarn is processed (from coarse to fine) through the cooperation of the back roller group, the middle roller group, and the front roller group. Subsequently, several yarns output from the front roller group are wound onto corresponding spindles. The front roller group includes a left front roller and a right front roller rotatably connected to the support frame, and each front roller is relatively long (refer to the existing patent: A spinning machine, publication number "CN 211645484U", publication date: 2020.10.09). During operation, each front roller is equipped with a rotating device at both ends to drive its rotation (the principle of the rotating device driving the front roller to rotate is referenced in the existing patent: A Simple Roller Drive Assembly, Publication No.: CN 116446081A, Publication Date: 2023.07.18). When each front roller is working, it is driven by two rotating devices to drive the two ends of the roller, thereby driving the overall rotation of the roller. However, due to the long length of the roller, the driving force gradually weakens along the length of the roller. Therefore, the rotation speed in the middle area of ​​the roller lags behind the rotation speed at both ends, resulting in uneven and unstable overall rotation speed of the roller. Consequently, the speed at which the yarn in the middle area of ​​the roller winds around the spindle lags behind the speed at which the yarn winds around the spindle at both ends, reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a roller device for spinning machinery, which solves the problem that the overall rotation speed of the existing roller is uneven and unstable, causing the consistency of the yarn winding around the spindle in the middle area of ​​the roller to lag behind that of the yarn winding spindle at both ends, thus reducing production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a roller device for spinning machinery, including a roller assembly and drive components disposed at both ends of the roller assembly for rotating the rollers in the roller assembly. The roller assembly includes a front group and a rear group arranged sequentially along the length direction. The drive components are disposed at the far ends of the front group and the rear group, and auxiliary drive components are disposed at the near ends of the front group and the rear group. One of the auxiliary drive components cooperates with the drive component disposed on the front group to drive the front group to rotate, and the other auxiliary drive component cooperates with the drive component disposed on the rear group to drive the rear group to rotate.

[0005] Furthermore, the auxiliary drive assembly includes a gear transmission component and a drive motor that drives the gear transmission component, and the rollers in the front group and the rear group are respectively connected to the corresponding gear transmission components.

[0006] Furthermore, the auxiliary drive assembly also includes a protective housing, and the gear transmission is disposed within the protective housing.

[0007] Furthermore, the protective box is equipped with a heat dissipation mesh.

[0008] Furthermore, the length of the front group is the same as the length of the rear group.

[0009] Furthermore, the length of the front group is greater than the length of the rear group, or the length of the rear group is greater than the length of the front group.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a roller device for spinning machinery, including a roller assembly and drive components disposed at both ends of the roller assembly for driving the roller assembly to rotate. The roller assembly includes a front group and a rear group arranged sequentially along its length. The drive components are disposed at the far ends of the front group and the rear group, and auxiliary drive components are disposed at the near ends of the front group and the rear group. One auxiliary drive component cooperates with the drive component disposed on the front group to drive the front group to rotate, and the other auxiliary drive component cooperates with the drive component disposed on the rear group to drive the rear group to rotate. The driving force provided by the auxiliary drive components cooperating with the drive components is relatively large. Although this large driving force gradually weakens along the length of the front or rear group, it still ensures that the rotation speed in the middle area of ​​the front or rear group is the same as the rotation speed at the end, thus ensuring the uniformity and stability of the overall rotation speed. This ensures that each yarn fed by this roller device winds onto the spindle at a consistent speed, improving yarn production efficiency. Attached Figure Description

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the roller device or element for the spinning machinery referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Example 1 refer to Figure 1 , Figure 2 and Figure 3This example provides a roller device for spinning machinery, comprising a roller assembly 1 and drive components 2 disposed at both ends of the roller assembly 1 for rotating the rollers in the roller assembly 1. The drive components 2 can be electronic drafting drive components or mechanical drafting drive components. The roller assembly 1 includes a front group 11 and a rear group 12 arranged sequentially along its length. In this example, the length of the front group 11 and the rear group 12 are the same. Both the front group 11 and the rear group 12 include a rear roller 111, a middle roller 112, and a front roller 113. Drive components 2 are disposed at the far ends of the front group 11 and the rear group 12, and auxiliary drive components 3 are disposed at the near ends of the front group 11 and the rear group 12. The auxiliary drive components 3 are located in the middle of the roller assembly 1. One auxiliary drive component 3 cooperates with the drive component 2 disposed on the front group 11 to rotate the front group 11, and the other auxiliary drive component 3 cooperates with the drive component 2 disposed on the rear group 12 to rotate the rear group 12. The auxiliary drive assembly 3 includes a gear transmission component and a drive motor that drives the gear transmission component. The gear transmission component consists of multiple gears that transmit power between the motor and the rollers, commonly known as a gearbox (the auxiliary drive assembly is not shown in the figure). The rear roller 111, the middle roller 112, and the front roller 113 are connected to the gear transmission component.

[0017] refer to Figure 1 , Figure 2 and Figure 3 During operation, the drive assembly 2 and auxiliary drive assembly 3 that drive the front group 11 and the rear group 12 are first adjusted to ensure that the drive speeds of the drive assembly 2 and the auxiliary drive assembly 3 are the same. Then, through the cooperation of the drive assembly 2 and the auxiliary drive assembly 3, the rear roller 111, the middle roller 112 and the front roller 113 in the corresponding front group 11 and rear group 12 are rotated. The drive force provided by the auxiliary drive assembly 3 in cooperation with the drive assembly 2 is relatively large. Although this relatively large drive force gradually weakens along the length of the front group 11 or the rear group 12, it can still ensure that the rotation speed of the middle area of ​​the front group 11 or the rear group 12 is the same as the rotation speed of the end. This ensures the uniformity and stability of the overall rotation speed, so that the speed at which each yarn conveyed by this roller device winds onto the spindle is consistent, thereby improving yarn production efficiency.

[0018] refer to Figure 1 and Figure 4 The auxiliary drive assembly 3 also includes a protective box 4 for protecting the gear transmission components. The gear transmission components are housed inside the protective box 4. The protective boxes 4 in the two sets of auxiliary drive assemblies 3 can be set independently or attached to each other. The drive motor is also installed inside the protective box 4. The protective box 4 protects the gear transmission components and prevents cotton lint from falling from the yarn from accumulating on the gear transmission components.

[0019] refer to Figure 1 and Figure 4After prolonged operation, gear transmission components are prone to generating heat. A heat dissipation mesh 6 is installed on the protective box 4 to dissipate and cool the generated heat, preventing the temperature inside the protective box 4 from becoming too high and affecting the normal operation of the gear transmission components.

[0020] Example 2 This embodiment has a basically the same structure as Embodiment 1, except that: refer to Figure 5 The length of the front group 11 is greater than the length of the rear group 12, or the length of the rear group 12 is greater than the length of the front group 11. In this example, the length of the front group 11 is greater than the length of the rear group 12. In this case, the auxiliary drive component 3 is closer to the rear group 12. The length of the front group 11 can be selected based on the condition that the uniform and stable rotation of the front group can be ensured by the cooperation of the drive component 2 and the auxiliary drive component 3. The length of the rear group 12 is shorter, and the uniform speed and stability of the rotation of the rear group 12 can be ensured by the drive component 2 connected to the rear group 12. In addition, in this roller assembly structure, if the uniform speed of the rotation of the rear group 12 can be ensured by the drive component 2 connected to the rear group 12 alone, then the auxiliary drive component 2 connected to the rear group 12 can be turned off and does not need to work.

[0021] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
